管道基礎(chǔ)一般叫管座混凝土，有些也叫包管混凝土是直接包裹或者澆筑在管道下的?；炷翂|層是管道構(gòu)筑物基礎(chǔ)下鋪設(shè)的。兩者區(qū)別還是比較大的。一般管座混凝土下是砂墊層居多，混凝土墊層多用于檢查井基礎(chǔ)。管道基礎(chǔ)必須是管道下直接包裹或者是直接接觸到管道的。管道基礎(chǔ)有混凝土的（也有砂石的）。而混凝土墊層必須是在基礎(chǔ)和地基之間的那塊。起保護基礎(chǔ)、改善地基作用的。雖然在預(yù)算時砂石基礎(chǔ)常常套用砂石墊層定額，但實際是兩個不同的東西。四川多聯(lián)市政管道規(guī)格尺寸齊全市政管道基礎(chǔ)與管道墊層在所處位置和作用上有所不同。</p><div

墊層道使用條件和規(guī)版定如下：1、路基經(jīng)常處于潮濕和過濕狀態(tài)的路段，以及在季節(jié)性冰凍地區(qū)產(chǎn)生冰凍危害的路段應(yīng)設(shè)墊層。2、墊層材料有粒料和無機結(jié)合料穩(wěn)定土兩類。粒料包括權(quán)天然砂礫，粗砂，爐渣等。采用粗砂和天然砂礫時，小于；采用爐渣時，小于2mm的顆粒含量宜小于20%。3、墊層厚度要按當(dāng)?shù)亟?jīng)驗確定，在季節(jié)性冰凍地區(qū)路面總厚度小于防凍**小厚度時，應(yīng)以墊層材料補足。1、墊層是基礎(chǔ)與地基土體之間的一個中百間層，其作用是起到保護基礎(chǔ)的作用。2、基礎(chǔ)是承重的結(jié)構(gòu)層。市政管道的基礎(chǔ)與管道的墊層，也是上述的概念。因此，市政管道的基礎(chǔ)是直接承受管道重量的一部分。而墊層不是，墊層只是為了做管道基礎(chǔ)而度設(shè)置的一層“措施層”。

閉水試驗不合格管道滲水不僅影響管道的正常使用，嚴(yán)貢時可對周圍重要建筑物引起破壞。引發(fā)管道滲水的主要原因有基礎(chǔ)不均勻沉降，使用了質(zhì)量較差的管材、選用了形式不當(dāng)?shù)墓艿澜涌诨蚱涫┕べ|(zhì)量差等原因基礎(chǔ)的不均勻沉降，會使影響段管道與基面的接觸發(fā)生變化，引起的部分竹道應(yīng)力高度集中，發(fā)生拉裂或壓裂，主要是拉裂，從而引起滲水;質(zhì)量不佳的管道，若是出現(xiàn)管道振動不良受力等情況，結(jié)合不均勻沉降引起的應(yīng)力集中，更容易發(fā)生破壞;管道接口不合格或是密封工作不到位，會在接口這個密封薄弱部位出現(xiàn)漏水;此外，較差的施工質(zhì)量如管道安放不按規(guī)范.地基加固不符要求.均是出現(xiàn)竹道破裂、引發(fā)滲漏的主要原因。路基經(jīng)常處于潮濕和過濕狀態(tài)的路段，以及在季節(jié)性冰凍地區(qū)產(chǎn)生冰凍危害的路段應(yīng)設(shè)墊層。</p><div
